Change the IGMP Snooping Configuration settings
Multicasting is used to support real-time applications such as video-conferencing or
streaming audio. A multicast server doesn’t have to establish a separate connection
to each client; it only broadcasts its service to the network. Using this approach will
significantly increase broadcast traffic on the network. This switch can use IGMP to
filter multicast traffic. IGMP snooping can be used to passively monitor or snoop the
packets exchanging between multicast hosts and clients. Then it can set its filters. You
can use the IGMP Snooping Configuration page to configure Global and Port Related
settings to control the forwarding of multicast traffic. This can decrease broadcast
traffic to improve the network performance.
You can access the screen by clicking

Description
Global Configuration
Snooping
Enabled
Control whether the IGMP snooping is enabled.
Unregistered
IPMCv4
Flooding
Enabled
Enable unregistered IPMCv4 traffic flooding. The flooding control
takes effect only when IGMP Snooping is enabled. When IGMP
Snooping is disabled, unregistered IPMCv4 traffic flooding is
always active in spite of this setting.
IGMP SSM
Range
SSM (Source-Specific Multicast) Range allows the SSM-aware
hosts and routers to run the SSM service model for the groups in
the address range.
Leave Proxy
Enable
Enable IGMP Leave Proxy. This feature can be used to avoid
forwarding unnecessary leave messages to the router side.
Proxy Enabled
Enable IGMP Proxy. This feature can be used to avoid forwarding
unnecessary join and leave messages to the router side.
Port Related Configuration
Port
Port identifier.
Router Port
Specify which ports act as router ports. A router port is a port
on the Ethernet switch that leads towards the Layer 3 multicast
device or IGMP querier. If an aggregation member port is
selected as a router port, the whole aggregation will act as a
router port.
Fast Leave
Enable the fast leave on the port.
